Pi 4, this has been consistent with at least the last three or four updates, don’t know if more. Audio out to amp via HDMI, from there video to TV.
Somewhere in the range of every fifth to tenth time I pause a video, when I resume there is no audio. Searched for similar threads, but they all seem to describe a delay in audio resumption. In my case, no audio. Can play for minutes with no audio.
Pretty simple solution, stop video (as opposed to pause) and then resume from last position and all is good, usually with a 10-second rewind to get back to where I was when I paused.
A very minor annoyance, it doesn’t happen every time, and the fix is pretty easy when it does, but if anyone has ideas/settings to check would appreciate fixing it. Don’t even know if it is something with OSMC or with the AV gear.
